The big idea

A measurement needs both a number and a unit. The unit tells someone else what was measured, while a sensible instrument and scale help make the number useful.

Try to explain…

Choose a suitable measuring instrument, read its scale and convert a length into metres without changing the physical distance.

Work through an example Think first, then reveal

A strip of card begins at the 4.0 cm mark of a ruler and ends at 36.0 cm. Find its length in centimetres and metres. Use 100 cm = 1 m.

Reveal the reasoning and answer
  1. Subtract the starting reading: length = 36.0 − 4.0 = 32.0 cm. The final scale reading alone is not the length.
  2. Convert centimetres to metres by dividing by 100: 32.0 / 100 = 0.320 m. Keep the unit beside the number.

The strip is 32.0 cm long, or 0.320 m.

Pathway notes & suggested depth

These original starters support learning; they do not establish complete coverage of an IB syllabus.

Year ranges are flexible suggestions, not a fixed IB syllabus. Adapt depth and sequence with your teacher.

Scientific inquiry and measurement are included here as foundations used throughout every visual group; all original inquiry topics remain available.

Framework & official guidance Suggested pathway, not a fixed syllabus →

A flexible route through Middle Years Programme sciences

A suggested GioPhysics pathway, not a prescribed IB Physics syllabus. Schools may reorder, combine or extend topics. Year filters use the existing suggested ranges and do not limit what a school may teach.

The eight visual groups help you browse; the original 20-chapter sequence remains available above and in the school planning pathway. Inquiry, measurement and evidence run through every group. Teachers choose suitable depth and use the applicable year-specific assessment descriptors.

GioPhysics is independently developed and is not endorsed by the International Baccalaureate Organization. Our questions, practice papers and project prompts are original teaching resources, not official IB papers or assessed student exemplars.
